PUMP.

SPECIFICATION forming part of Letters Patent No. 697,046, dated April 8, 1902.

Application filed April 13,1901. Serial No. 55,759. (No model.)

To all whom, t nur?! concern:

Be it known that I, ELIIVARREN, a citizen of the United States, residing at Eldorado, in the county of Butler and State of Kansas, have invented new and useful Improvements in Pumps, of whichthe following is aspeciication.

My invention relates to pumps of the class in which two'valved plungers are employed, thelower one receiving the water from the well and delivering it through the upper valve to the discharge-spout.

The object of the invention is to simplify the mechanism for reciprocating the plunger-s and to provide a simple and effective construction of pump to insure a free fiow of water with little eiiort on the part of the operator.

The construction of the improvement will be fully described hereinafter in connection with the accompanying drawing,formingpart of this specification, and its novel features will be defined in the appended claim.

I have fully and clearly illustrated the invention in the accompanying drawing, showing the invention in vertical longitudinal section only, one side of the frame containing the plunger and piston actuating mechanism being shown.

It will be premised that the improved mechanism may be applied to any pump provided with alternating plunger-rods and pistons or suckers, substantially as indicated in Vthe drawing.

Referring to the drawing, 1 designates a pump barrel or cylinder inelosed by a stock 2 for such distance as may be desired and constituting a support for a frame, wherein is suitably mounted the actuating mechanism. This frame comprises duplicate vertical side pieces 3, (one only being shown,) forming part of the base or stock 2 or being mounted thereon and secured thereto by any suitable means. The side pieces of the frame extend to such height as may be required to provide ample movementfor the head-blocks of the plunger-rods. The side pieces 3 are rigidly connected at the top by a cross-piece 1i, as shown in the drawing. To the inner side of each of the bars 3 are secured parallel cleats 5, 6, and 7, forming guideways 8 and 9 to receive sliding blocks 10 and'll.

12 designates the pump-handle, which is fulcrumed upon a cross-pin 13, secured to the side bars 3. The handle 12 is connected to the blocks 10 and ll by rods 14 and 15, the lower ends of said rods being attached to a vertically-rocking lever or handle 12 on opposite sides of the fulcrum 13. The lower end portions of the bars 14 15 are flattened, as at a, and provided with a series of apertures b, whereby the relative positions ofthe pistons may be accommodated to the depth of the well.

16 and 17 designate pump-rods, the upper ends of which are secured, respectively, to the inner sides of the blocks 10 and 11. To the lower end of each of the rods 16 and 17 is secured a plunger, (designated by the numerals 18 and 19, respectively.) The rod 17 extends down through the plunger 18 of the rod 16, and each of said plungers is provided with an outwardly-opening valve 20.

21 designates the discharge-spout of the pump.

The operation of the mechanism constructed as thus described will be readily understood. The upward movement of the rod 17 causes its plunger 19 to elevate water by suction and deliver it through the plunger 1S, which raises the water to the discharge-spout. The sliding blocks lO and 11 have a free reciprocating movement within the guideways 8 and 9, insuring the proper reciprocating motion ofthe pump-rods with the minimum friction.

I claim- In a pump-actuating mechanism, the combination with the pump barrel or stock, and upper and lower pistons in the barrel, of vertical side pieces provided with parallel vertical cleats in their inner faces arranged with guideways between them, head-blocks slid ingly disposed in said guideways, rods 14, 15, secured to and depending from each of said blocks, a vertically-rocking handle fulcrumed between the said side pieces and pivotally connected to the lower end of said rods 14, 15, and plunger-rods having their upper ends fastened to the sliding blocks and their lower ends secured to the upper and lower pistons, respectively.

In testimony whereof I affix my signature in presence of two witnesses.

ELI VARREN.
